Vilitra 40 mg contains Vardenafil, a phosphodiesterase type 5 (PDE5) inhibitor used for erectile dysfunction. Its mechanism of action is centered on improving blood flow to the penis during sexual stimulation. Mechanism of action (step-by-step) Sexual stimulation triggers nitric oxide (NO) release When a man is sexually aroused, nerve endings in the penis release nitric oxide. Nitric oxide increases cGMP levels Nitric oxide activates an enzyme that produces cyclic guanosine monophosphate (cGMP). This chemical relaxes smooth muscle in blood vessels. cGMP causes blood vessel relaxation The smooth muscles in Vilitra 40 mg arteries relax, allowing increased blood flow into erectile tissue, producing an erection. Role of PDE5 enzyme Normally, the enzyme PDE5 breaks down cGMP, ending the erection. How vardenafil works Vardenafil in Vilitra 40 mg blocks PDE5, preventing the breakdown of cGMP. ? This allows cGMP to stay active longer ? Blood vessels remain relaxed longer ? Stronger and more sustained erection occurs during sexual stimulation Key point about Vilitra 40 mg It does not create an erection on its own It enhances the natural erectile response to sexual stimulation 40 mg is a high dose, typically used only when lower doses are insufficient or under strict medical guidance Simple summary Vilitra 40 mg works by blocking PDE5 enzymes so that blood vessels in the penis stay relaxed longer, allowing improved blood flow during sexual arousal and supporting erection maintenance. If you want, I can compare how vardenafil differs from tadalafil (like Vidalista) in duration, onset, and strength.
